parasymp receptor actions

Question 1

a1

Answer 1

Most vascular smooth muscle (innervated) –> Contraction
Pupillary dilator muscle–>Contraction (dilates pupil)
Prostate–>Contraction
Heart–>Increases force of contraction

Question 2

a2

Answer 2

Postsynaptic CNS neurons–>multiple
Platelets–>Aggregation
Adrenergic and cholinergic nerve terminals–>Inhibits transmitter release
Some vascular smooth muscle–>Contraction
Fat cells–>Inhibits lipolysis

Question 3

B1

Answer 3

Heart, juxtaglomerular cells–>Increases force and rate of contraction; increases renin release

Question 4

B2

Answer 4

Respiratory, uterine and vascular smooth
muscle–>Promotes smooth muscle relaxation
Skeletal muscle–>Promotes potassium uptake
Human liver–>Activates glycogenolysis and
gluconeogenesis

Question 5

B3

Answer 5

Bladder–>Relaxes detrusor muscle

Fat cells–>Activates lipolysis

Question 6

D1

Answer 6

Smooth muscle–>Dilates renal blood vessels

Question 7

D2

Answer 7

Nerve endings–>Modulates transmitter release
